[Resolved]  Hero Motocorp — defective product and inaccurate service

My husband (Mr. Alok dikshit) had purchased hero maestro edge on 19/03/2018. After a year (I. E. June, 2019), its alternator (Rect) started creating problem, due to which we have to purchase a new battery (As without battery, maestro's ignition does not work). So, for the same we had give our bike for servicing to the authorized service center where they in first instance (Without checking) refuse to understand the problem of alternator and handed over the bike by charging the battery to us. But when the problem reappears after 2 days, they accepted the bike for checking and replace the alternator (Rect) for which we had paid rs. 530/- (Proof attached). And again, within a year we are facing the same problem and due to which we are unable to move and go to purchase necessary items in this pandemic situation as well as we cannot go to the service centre to make it repaired.
It is really very unfortunate that why the same problem is repetitively arising within a year if the service centre had given us the genuine product.
Please solve this problem and if possible please replace the item with the genuine product which last long and the same problem does not reappear.
